Many critics of conventional economics have argued, with considerable justification, that the assumptions underlying neoclassical theory bear little resemblance to the world we know. These critics, however, have been too quick to assert that this shows that mainstream economics can never be of any use. Recent progress in the technology of space travel, as well as the prospects of the use of space for energy production and colonization (O'Neill 1976) make this assertion doubtful; for they raise the distinct possibility that we may discover or construct a world to which orthodox economic theory applies.

I do not propose to develop a theory which is universally valid, but it may at least have some galactic relevance.

In a year when so many of Krugman's recent newspaper writings just strike me as so, well, depressing, I'm delighted to stumble across such a gem. In his discussion of which time frame to use in calculating the "present value" of the goods in interstellar trade, he sets forth this little treasure: "This is an inertial problem -- which becomes a weighty problem in a gravitational field -- requiring an economic analysis, provided in the next section" (3).

As an "oppressed assistant professor, caught up in the academic rat race," well, it seems as if he knew how to have a bit of fun with it, no?posted by deejay jaydee at 1:21 PM on March 11, 2008

A solution is derived from economic theory, and two useless but true theorems are proved.

Heh. But he ignored the work of G. Harry Stine, particularly The Third Industrial Revolution .... Yes, yes, it was published one year after the paper, but you have to take time compression near lightspeed into account.posted by dhartung at 1:32 PM on March 11, 2008

So, we're outsourcing to Proxima Centauri now?

Hmmmm. I think he did not deal with the issue of the effects of coupons for cheap OJ at light speed effectively (lol).posted by never used baby shoes at 2:21 PM on March 11, 2008

This paper, then, is a serious analysis of a ridiculous subject, which is of course the opposite of what is usual in economics.

Now that's worthy of a t-shirt.posted by Jakey at 2:54 PM on March 11, 2008

Interplanetary trade ... can be treated in the same framework as interregional and international trade. Among the authors who have not pointed this out are Ohlin (1933) and Samuelson (1947).

I don't have my Samuelson handy, but I'm sure it's in there. Damn near everything else is.... Fun post - he's got some good jokes in there.posted by dilettanti at 3:31 PM on March 11, 2008

Considering how many geeks are hard-core free-marketeers, this may be the only possible way for Krugman to increase his Geek Cred. But it works!posted by wendell at 3:48 PM on March 11, 2008

In the references he cites a paper called "Theory Capital and Travel Light-than-Faster" which of course is published 10 years after he wrote this paper.posted by JackFlash at 4:39 PM on March 11, 2008 [2 favorites]

I will assume, then, that future futures markets are, well, futuristic in their development. In fact, I will assume that investors, human or otherwise, are able to make perfect forecasts of prices over indefinite periods.
